GALFACTS：G-ALFA连续Transit调查
GALFACTS: The G-ALFA Continuum Transit Survey
摘要：
GALFACTS项目正在使用阿雷西博望远镜上的L波段七馈源阵列接收器系统，对阿雷西博可见的30%天空进行成像光谱偏振测量。GALFACTS观测将产生角分辨率为3.5“的全斯托克斯图像立方体，具有覆盖1225 - 1525 MHz的数千个光谱通道，带平均灵敏度为90 μ J，允许对偏振辐射和法拉第旋转进行灵敏成像，可以从漫射发射和对河外源的高密度网格进行测量。星系将是对银河系偏振辐射成像的一个重大观测进展，并将为探索银河系磁场和磁离子介质的性质提供一个丰富的新数据库。
英文摘要：
The GALFACTS project is using the L-band seven feed array receiver system on the Arecibo telescope to carry out an imaging spectro-polarimetric survey of the 30% of the sky visible from Arecibo. GALFACTS observations will create full-Stokes image cubes at an angular resolution of 3.5', with several thousand spectral channels covering 1225 - 1525 MHz, and band-averaged sensitivity of 90 uJy, allowing sensitive imaging of polarized radiation and Faraday Rotation Measure from both diffuse emission and against a high density grid of extragalactic sources. GALFACTS will be a major observational advance in imaging of the polarized radiation from the Milky Way and will provide a rich new database for exploration of the magnetic field of the Galaxy and the properties of the magneto-ionic medium.
